Description
Technical field
The present invention relates to building field, specifically refer to a kind of concrete folding insulation side bar.
Background technology
At present; Research to the building masonry wall insulation both at home and abroad is gradually improved; Building masonry wall and the lower thermal insulation material of coefficient of thermal conductivity are fixed as one increasing the evenly heat resistance of body of wall, thus reach insulation or effect of heat insulation become a kind of general engineering way.Simultaneously, because it is stronger to be in the reinforced concrete beam heat-transfer capability of exterior wall periphery, be the position that cold and hot bridge effect takes place in the building easily, therefore, and the generation of cold and hot bridge effect in the building, it is very necessary that beam is carried out corresponding thermal insulation structure measure.But the insulation way to beam is complicated now, and cost is higher, can not extensively be promoted the use of.And so-called superposed beam is the beam of disturbing concrete at twice, in precasting yard, carries out for the first time, makes precast beam; Carry out at the construction field (site) for the second time, after precast member board is shelved on the precast beam, waters the concrete of smashing beam top again and make floor and beam connect into integral body.How precast beam is made T section or square-section at present, but it is from great, the lifting transportation is inconvenient, and the bean column node place connects weakness.
Summary of the invention
In view of this; The invention provides a kind of concrete folding insulation side bar; This concrete folding insulation side bar comprises prefabricated thermal insulation side bar, precast member board, handling reinforcement, concrete folding layer; The prefabricated thermal insulation side bar comprises insulation layer longitudinal socket, insulation layer slot lateral wall, insulation layer, is embedded with longitudinal stress reinforcing bar, stirrup in the precast beam.This concrete folding insulation side bar heat-insulating property is good, and the measure of prefabricated thermal insulation side bar thermal insulation structure is simple, is convenient to mass production, easy construction, and labor savings, cheap.Said precast beam together is built up the good beam slab system of globality with the precast member board of shelving on it simultaneously, and this superimposed insulation side bar can carry out effectively high-strength being connected with post.
To achieve these goals; The present invention adopts following technical scheme: a kind of concrete folding insulation side bar; This concrete folding insulation side bar comprises prefabricated thermal insulation side bar, precast member board, handling reinforcement, concrete folding layer, and the prefabricated thermal insulation side bar comprises insulation layer longitudinal socket, insulation layer slot lateral wall, insulation layer, is embedded with longitudinal stress reinforcing bar, stirrup in the precast beam; Said prefabricated thermal insulation side bar is established longitudinal socket, is inserted with insulation layer in the longitudinal socket.
Further in technical scheme of the present invention, be preset with tension member in the longitudinal socket of said prefabricated thermal insulation side bar, the tension member two ends are stretched into respectively in insulation layer slot lateral wall and the precast beam lateral wall; In the insulation layer slot lateral wall built-in fitting is arranged, the built-in fitting other end stretches in the cast-in-situ concrete overlapping layers; The precast beam end form is set to groove or the middle part adds groove or the inclined-plane of indulging rib; Precast beam beam body is provided with hollow parts, and the hollow parts termination is provided with the end plug.
Concrete folding insulation side bar provided by the invention through the prefabricated thermal insulation side bar is provided with longitudinal socket, is inserted with insulation layer in the longitudinal socket; Make superposed beam have good heat-insulating property; And the prefabricated convenience of prefabricated thermal insulation side bar, cost is not high, during construction; Needn't take the thermal insulation structure measure to side bar separately again, it is very easy to construct.During the cast-in-situ concrete overlapping layers, insulation layer slot lateral wall can also be worked as side template and used, and needn't install concrete folding layer side template, has reduced the labour, has reduced construction cost on precast beam and precast member board.Simultaneously, the precast beam end form is set to groove or inclined-plane, has increased the contact area of new-old concrete, thereby has guaranteed the bonding strength at bean column node place.This insulation side bar can extensively be suitable for industry and civilian construction field.
